4. INSTRUCTIONS Fig.1 Alfa Romeo 1.4, 1.6, 1.8 & 2.0 Twin Spark + 2.0JTS petrol engines. 4.1 General Guide - Setting & Locking engines. Timing belt replacement on these Alfa Romeo twin cam engines is carried out with the crankshaft at TDC No.1 cylinder, established by using VS1404 TDC Position Tool together with a Dial Gauge (AK9634M), to determine the piston position. 4.1.1 VS1404 TDC Position Tool - Associated Tool - not in kit. The correct engine/crank TDC position is established using VS1404 Tool together with a suitable Dial Gauge such as AK9634M. VS1404 Tool determines when the piston of No.1 cylinder is at its highest point - NOTE: must be when it is on its ignition stroke. Remove the spark plugs and install the Dial Gauge into VS1404 and secure with the thumbscrew. Screw the VS1404 fully into the centre spark plug hole of No.1 cylinder, taking care not to over tighten (Fig.1). By turning the crankshaft, in the normal direction of engine rotation, the piston will raise the indicator pin of VS1404 and in turn, move the needle of the Dial Gauge. TDC is achieved when the Dial Gauge needle reaches its highest reading and starts to move in the reverse direction. Check that all timing marks align. Fig.2 4.1.2 Camshaft timing. The camshafts are retained in their 'timed' positions by use of Camshaft Setting Plate Assemblies which are fixed on the engine in place of designated bearing caps, at specified cylinder locations (Fig.2). The VS4910 Timing Kit is based on the unique AL-Fi Camshaft Setting Plate System. The AL-Fi range of Universal Camshaft Setting Plates provide wide application coverage across engine ranges by utilising common Support Blocks - one for all Inlet Camshafts, and one for all Exhaust Camshafts. Inter-changeable Setting Plates are mounted on to these Support Blocks. The position of the Setting Plates on the Support Blocks is adjustable in order to provide maximum coverage of engine ranges. Refer to 4.3 "The AL-Fi System Of Camshaft Setting Plates" 4.1.3 Both camshaft sprockets are released and free to turn on camshafts, when fitting new belt. Marks on the new belt are aligned to marks on the sprockets/pulley and fitted in the following order:- crankshaft, guide, camshaft (exhaust), camshaft (inlet), tensioner, water pump. Initially the timing belt tension is adjusted to maximum using Tensioner Adjuster VS1403/04. The camshaft sprocket bolts are then tightened, and all setting/locking tools removed and bearing caps re-fitted. The engine is rotated by hand, and VS1404 re-fitted to ensure return ` to TDC position. The tensioner is adjusted so the pointer aligns with hole, the engine is rotated again and returned to TDC. All timing marks must align. 4.1.4 For 2.0 engines the balancer shaft belt is tensioned using VS1409/03 Adjuster. With the crankshaft at TDC, align the balancer shaft timing marks and fit the belt. Adjust tensioner to position detailed below. 4.2 VS1403/04 Timing Belt Tensioner Adjuster & VS1409/03 Balancer Shaft Belt Tensioner Adjuster (Fig.3). 1403/04 Adjuster is used for all these twin cam engines. The correct final adjustment for the timing belt tensioner is with the pointer of the tensioner aligned with the reference hole - see fig.3. VS1409/03 adjusts the tensioner of the balance shaft belt on 2.0 engines. The correct final position is with the hole on the tensioner aligned to the centre point of the tensioner movement - see fig.3. Fig.3
4.3 The AL-Fi System of Camshaft Setting Plates. The Al-Fi range of Universal Camshaft Setting Plates provides wide application coverage across engine ranges by utilising common Support Blocks - one for all Inlet camshafts, and one for all Exhaust camshafts. Interchangeable Setting Plates are mounted on to these Support Blocks. The position of the Setting Plates on the Support Blocks is adjustable in order to provide coverage of a range of engines. The required Setting Plate position on the Support Block, is accurately achieved, and maintained, via the 'location pin' which is inserted through a numbered location hole in the Support Block and through a hole in the Setting Plate. When mounted on the engine, this assembly fixes the position of the camshaft lobe to achieve correct camshaft timing position. Fig.4 Fig.5 4.4 Selecting the correct Al-Fi parts and assembling the Camshaft Setting Plate system for use. 4.4.1 The Inlet Camshaft Setting Plate Assembly. Select the "INLET" Support Block (Fig.4). Refer to the Data Chart to establish which Setting Plates are required for the application. = Plates "A" and "B" (Fig.5). Fix the Setting Plates to the "INLET" Support Block with the securing screws (Do not tighten fully at this stage) (Fig.6). Note: Plate "A" to the left and Plate "B" to the right, with the "A" and "B" lettering visible. Refer to Data Chart to establish which hole number location is required for this application. = Plate A location "6" and Plate B location "6" (Fig.5). Select the Location Pins/Chain Assembly and pass the pins through the correct hole locations in the Support Block and into the Setting Plates (Fig.7). Retain the Location Pins in place by applying pressure to the sides of the Setting Plates whilst fully tighten the setting plate Securing Screws using the allen key provided in the kit (Fig.8). 4.4.2 The Exhaust Camshaft Setting Plate Assembly. Select the "EXHAUST" Support Block (Fig.9). Refer to Data Chart to establish which Setting Plates are required for the application. = Plates "C" and "D" (Fig.5). Fix the Setting Plates to the "EXHAUST" Support Block with the securing screws (Do not tighten fully at this stage) (Fig.10). Note: Plate "C" to the left and Plate "D" to the right, with the "C" and "D" lettering visible. Refer to Data Chart to establish which hole number location is required for this application. = Plate C location "3" and Plate D location "3" (Fig.5). Fig.6 Fig.8 Fig.10 Fig.7 Fig.9 Fig.11 Select the Location Pins/Chain Assembly and pass the pins through the correct hole locations in the Support Block and into the Setting Plates (Fig.11). Retain the Location Pins in place by applying pressure to the sides of the Setting Plates whilst fully tighten the setting plate Securing Screws using the allen key provided in the kit (Fig.12). Fig.12
4.5 Fig.5 Fitting the Al-Fi Camshaft Setting Plate Sets to the engine. Camshaft Setting Plate Assemblies are fixed in place of designated bearing caps, at specified cylinders. Refer to Data Chart to establish at which cylinder position the "INLET" and the "EXHAUST" Setting Plate Assemblies are to be fitted on to the camshafts for the model/engine. = Inlet "Cylinder No.2" and Exhaust "Cylinder No.3" (Fig.5). 4.6 For timing belt replacement applications with the old timing belt still in-situ/engine timing correct. Fig.13 Fig.14 Fig.15 Fig.16 Fig.17 Fig.18 With the crankshaft correctly positioned at TDC No.1 cylinder, the camshaft lobes should be in the correct timed position to accept the Al-Fi Setting Plate Assemblies. Remove the bearing caps of the inlet and exhaust camshafts at the appropriate cylinder locations. NOTE: Clearly mark which is the inlet and exhaust, and keep clean at all times (Fig.13). Place the Inlet and Exhaust Al-Fi Setting Plate Assemblies in position over the appropriate camshaft lobes. NOTE: Ensure that the fixing holes in the Support Blocks match the offset bearing cap holes in the cylinder head (Fig.14). When viewed from the camshaft sprockets, the lettering on the Setting Plates should be visible. CHECK THAT THE BASES OF THE SUPPORT BLOCKS REST ON THE SURFACE OF THE CYLINDER HEAD AND THAT THE SETTING PLATES ARE ALIGNED WITH THE PROFILE OF THE CAMSHAFT LOBES (Fig.15). Insert the Flanged Securing Bolts (4) and tighten evenly to 10Nm (Fig.16). The belt tensioner can now be released and the old belt removed. NOTE: These Alfa Romeo and Fiat timing belt applications require the camshaft sprockets to be 'free to turn' on the camshaft, when fitting the new timing belt, and therefore it is necessary to slacken the camshaft sprocket bolts. WARNING: DO NOT use Al-Fi Camshaft Setting Plate Assemblies to counter-hold camshafts in position whilst releasing or tightening the sprocket bolts as this will damage the Setting Plates. Al-Fi Assemblies are for retention of timing position only. A suitable sprocket holding tool MUST BE used to counter-hold the sprockets. 4.7 For camshaft timing applications (when timing belt not in place). Al-Fi Setting Plate Assemblies can be used to 'set' the camshaft timing on these engines after engine overhaul or repair, and prior to installing a new belt. The preparation involved in establishing the model/engines, selecting the appropriate Al-Fi parts to create the correct camshaft setting plate assemblies, and determining the correct cylinder location, is exactly the same as described earlier. The appropriate cylinder locations should not have their camshaft bearing caps fitted. Look at the lobe profile form that has been created on the INLET Al-Fi Setting Plate Assembly and using a suitable Sprocket Holding Tool on the camshaft sprockets, turn the INLET camshaft until the camshaft lobe at the appropriate cylinder location is approximately in the same orientation as the Setting Plate Assembly (Fig.17). Place the INLET and EXHAUST Al-Fi Setting Plate Assemblies in position over the appropriate camshaft lobes. NOTE: Ensure that the fixing holes in the Support Blocks match the offset bearing cap holes in the cylinder head (Fig.18).
Using the Sprocket Holding Tool, make any final adjustment required to the camshaft position so the lobe aligns with the Setting Plates (Fig.19). Whilst maintaining this position with the Holding Tool, CHECK THAT THE BASE OF THE SUPPORT BLOCK RESTS ON THE SURFACE OF THE CYLINDER HEAD AND THAT THE SETTING PLATES ARE ALIGNED WITH THE PROFILE OF THE CAMSHAFT LOBES, and insert the four Flanged Securing Bolts. Tighten evenly to 10Nm. Repeat the same procedure with the Exhaust Setting Plate Assembly/camshaft.When fitting the new timing belt the camshaft sprockets must be 'free to turn' on the camshaft and therefore it is necessary to slacken the camshaft sprocket bolts. WARNING: DO NOT use Al-Fi Camshaft Setting Plate Assemblies to counter-hold camshafts in position whilst releasing or tightening the sprocket bolts as this will damage the Setting Plates. Al-Fi Assemblies are for retention of timing position only. A suitable Sprocket Holding Tool MUST BE used to counter-hold the sprockets. When fitting the new timing belt the camshaft sprockets must be 'free to turn' on the camshafts and therefore it is necessary to slacken the camshaft sprocket bolts. Fig.19 4.8 Crankshaft Pulley Removal. VS1403/03 Flywheel Holding Tool (Crank Pulley removal) - Associated Tool - not in Kit. The crankshaft pulley must be removed in order to replace the timing belt. On 2.0 engines a centre bolt retains the crankshaft pulley and it will be necessary to firmly and safely 'lock' the flywheel when releasing and tightening the pulley bolt. Flywheel Holding Tool VS1403/03 can be used to 'lock' the flywheel on this application. Extend Your AL-Fi Application Coverage.
